Bulk Grading

[CardboardCollector]

I have a number of pre-war and vintage duplicates that I am looking to sell in order to support my collecting needs in the coming year. Having just gotten back into collecting after a really long hiatus, I have never submitted a card to a grading company and am looking for some advise.

Just trying to get a handle on the economics of grading and possible return on investment. I was thinking of getting cards in ex or higher graded along with higher end stuff regardless of grade. All others just sell as is.

One if my challenges is the cost of grading. I see that the different grading companies offer specials and have spoken with them about bulk discounts.

What are your experiences in submitting a large number of cards to for grading? A large number for me might breakdown to 50,100, 500 or more cards.

Have you submitted all at once or smaller groups over time?

What kind of discount off their published payment schedule have you seen?

It looks to me that some dealers seem to get an enormous discount?

Thanks in advance for reading this and responding to my questions.
